Introduction
Industrial inkjet inks — especially those used in CIJ, TIJ, and DOD systems — often contain flammable or volatile solvents like MEK, ethanol, or acetone. These materials are classified as dangerous goods (DG) and are subject to strict regulations for storage, handling, and international transport.
This guide provides essential best practices for storing and shipping ink safely, with a focus on UN codes, packaging standards, and compliance with international transport rules.
1. Why Ink Transport and Storage Safety Matters
Improper storage or handling of ink can lead to:
- Fire or explosion risks
- Ink degradation due to heat or sunlight
- Regulatory violations (customs delays, fines)
- Packaging damage and leaks
Manufacturers and distributors must understand the legal and technical requirements for each ink type.
2. Common UN Codes for Inkjet Ink Solvents
| UN Code | Material | Ink Example | Hazard Class |
|---|---|---|---|
| UN1210 | Printing ink, flammable (MEK-based) | C-V420MEK, C-W485WHITE | Class 3 (Flammable liquid) |
| UN1170 | Ethanol solution | C-V411ETH, C-MI5191 | Class 3 |
| UN1090 | Acetone | C-V480AC | Class 3 |
| UN1263 | Paint or paint-related material | Pigmented ink blends | Class 3 |
3. GHS Labeling and Packaging Requirements
All ink containers must comply with Globally Harmonized System (GHS) labeling standards:
- Hazard pictograms (flammable, irritant, etc.)
- Signal words: DANGER or WARNING
- Precautionary statements (P-codes)
- UN number and hazard class clearly printed
Container Best Practices:
- Use leak-proof HDPE or composite drums (1L, 5L, 20L)
- Seal with tamper-evident caps
- Place in secondary containment during transit
4. Storage Guidelines for Ink and Solvent
| Condition | Recommended Practice |
|---|---|
| Temperature | 10°C–30°C (avoid freezing or overheating) |
| Ventilation | Store in a well-ventilated room with no ignition sources |
| Sunlight | Keep away from direct sunlight to avoid chemical degradation |
| Shelf Life | Check expiry dates; rotate inventory FIFO |
| Fire Safety | Install Class B fire extinguishers; ground metal containers |
5. International Shipping Considerations
✔ Air Freight (IATA/ICAO)
- Follow IATA Dangerous Goods Regulations (DGR)
- Use UN-approved packaging with hazard labels
- Declare DG status in airway bill (AWB)
✔ Sea Freight (IMDG Code)
- Follow IMDG container labeling and manifesting rules
- Use strong drums and absorbent material in LCL shipments
✔ Road Transport (ADR – Europe, 49 CFR – US)
- Label pallets and ensure driver carries DG documents
- Comply with regional flammable goods quantity limits
